National Security Technologies LLC (United States), 2010Co-Authors: Programs, Nstec EnvironmentalAbstract:The Nevada National Security Site (NNSS) is located approximately 105 km (65 mi) northwest of Las Vegas, Nevada. The U.S. Department of Energy National Nuclear Security Administration Nevada Site Office (NNSA/NSO) is the federal lands management authority for the NNSS and National Security Technologies, LLC (NSTec) is the Management and Operations contractor. Access on and off the NNSS is tightly controlled, restricted, and guarded on a 24-hour basis. The NNSS is posted with signs along its entire perimeter. NSTec is the operator of all Solid Waste Disposal sites on the NNSS. The Area 5 Radioactive Waste Management Site (RWMS) is the location of the permitted facility for the Solid Waste Disposal Site (SWDS). The Area 5 RWMS is located near the eastern edge of the NNSS (Figure 1), approximately 26 km (16 mi) north of Mercury, Nevada. The Area 5 RWMS is used for the Disposal of low-level Waste (LLW) and mixed low-level Waste. Many areas surrounding the RWMS have been used in conducting nuclear tests. The site will be used for the Disposal of regulated Asbestiform Low-Level Waste (ALLW), small quantities of low-level radioactive hydrocarbon-burdened (LLHB) media and debris, LLW, LLW that contains Polychlorinated Biphenyl (PCB) Bulk Product Waste greater than 50 ppm that leaches at a rate of less than 10 micrograms of PCB per liter of water, and small quantities of LLHB demolition and construction Waste (hereafter called permissible Waste). Waste containing free liquids, or Waste that is regulated as hazardous Waste under the Resource Conservation and Recovery Act (RCRA) or state-of-generation hazardous Waste regulations, will not be accepted for Disposal at the site. Waste regulated under the Toxic Substances Control Act (TSCA) that will be accepted at the Disposal site is regulated asbestos-containing materials (RACM) and PCB Bulk Product Waste greater than 50 ppm that leaches at a rate of less than 10 micrograms of PCB per liter of water. The term asbestiform is used throughout this document to describe RACM. The Disposal site will be used as a depository of permissible Waste generated both on site and off site. All generators designated by NNSA/NSO will be eligible to dispose regulated ALLW at the Asbestiform Low-Level Waste Disposal Site in accordance with the DOE/NV-325, Nevada National Security Site Waste Acceptance Criteria (NNSSWAC, current revision). Approval will be given by NNSA/NSO to generators that have successfully demonstrated through process knowledge (PK) and/or sampling and analysis that the Waste is low-level, contains asbestiform material, or contains PCB Bulk Product Waste greater than 50 ppm that leaches at a rate of less than 10 micrograms of PCB per liter of water, or small quantities of LLHB demolition and construction Waste and does not contain prohibited Waste materials. Each Waste stream will be approved through the Radioactive Waste Acceptance Program (RWAP), which ensures that the Waste meets acceptance requirements outlined in the NNSSWAC

Application for a Permit to Operate a Class III Solid Waste Disposal Site at the Nevada Test Site Area 5 Asbestiform Low-Level Solid Waste Disposal Site
National Security Technologies LLC (United States), 2010Co-Authors: Programs, Nstec EnvironmentalAbstract:The NTS Solid Waste Disposal sites must be permitted by the state of Nevada Solid Waste Management Authority (SWMA). The SWMA for the NTS is the Nevada Division of Environmental Protection, Bureau of Federal Facilities (NDEP/BFF). The U.S. Department of Energy's National Nuclear Security Administration Nevada Site Office (NNSA/NSO) as land manager (owner), and National Security Technologies (NSTec), as operator, will store, collect, process, and dispose all Solid Waste by means that do not create a health hazard, a public nuisance, or cause impairment of the environment. NTS Disposal sites will not be included in the Nye County Solid Waste Management Plan. The NTS is located approximately 105 kilometers (km) (65 miles [mi]) northwest of Las Vegas, Nevada (Figure 1). The U.S. Department of Energy (DOE) is the federal lands management authority for the NTS, and NSTec is the Management and Operations contractor. Access on and off the NTS is tightly controlled, restricted, and guarded on a 24-hour basis. The NTS has signs posted along its entire perimeter. NSTec is the operator of all Solid Waste Disposal sites on the NTS. The Area 5 RWMS is the location of the permitted facility for the Solid Waste Disposal Site (SWDS). The Area 5 RWMS is located near the eastern edge of the NTS (Figure 2), approximately 26 km (16 mi) north of Mercury, Nevada. The Area 5 RWMS is used for the Disposal of low-level Waste (LLW) and mixed low-level Waste. Many areas surrounding the RWMS have been used in conducting nuclear tests. A Notice of Intent to operate the Disposal site as a Class III site was submitted to the state of Nevada on January 28, 1994, and was acknowledged as being received in a letter to the NNSA/NSO on August 30, 1994. Interim approval to operate a Class III SWDS for regulated asbestiform low-level Waste (ALLW) was authorized on August 12, 1996 (in letter from Paul Liebendorfer to Runore Wycoff), with operations to be conducted in accordance with the ''Management Plan for the Disposal of Low-Level Waste with Regulated Asbestos Waste.'' A requirement of the authorization was that on or before October 9, 1999, a permit was required to be issued. Because of NDEP and NNSA/NSO review cycles, the final permit was issued on April 5, 2000, for the operation of the Area 5 Low-Level Waste Disposal Site, utilizing Pit 7 (P07) as the designated Disposal cell. The original permit applied only to Pit 7, with a total design capacity of 5,831 cubic yards (yd{sup 3}) (157,437 cubic feet [ft{sup 3}]). NNSA/NSO is expanding the SWDS to include the adjacent Upper Cell of Pit 6 (P06), with an additional capacity of 28,037 yd{sup 3} (756,999 ft{sup 3}) (Figure 3). The proposed total capacity of ALLW in Pit 7 and P06 will be approximately 33,870 yd{sup 3} (0.9 million ft{sup 3}). The site will be used for the Disposal of regulated ALLW, small quantities of low-level radioactive hydrocarbon-burdened (LLHB) media and debris, LLW, LLW that contains PCB Bulk Product Waste greater than 50 ppm that leaches at a rate of less than 10 micrograms of PCB per liter of water, and small quantities of LLHB demolition and construction Waste (hereafter called permissible Waste). Waste containing free liquids, or Waste that is regulated as hazardous Waste under the Resource Conservation and Recovery Act (RCRA) or state-of-generation hazardous Waste regulations, will not be accepted for Disposal at the site. The only Waste regulated under the Toxic Substances Control Act (TSCA) that will be accepted at the Disposal site is regulated asbestos-containing materials (RACM). The term asbestiform is used throughout this document to describe this Waste. Other TSCA Waste (i.e., polychlorinated biphenyls [PCBs]) will not be accepted for Disposal at the SWDS. The Disposal site will be used as a depository of permissible Waste generated both on site and off site. All generators designated by NNSA/NSO will be eligible to dispose regulated ALLW at the Asbestiform Low-Level Waste Disposal Site in accordance with the U.S. Department of Energy, Nevada Operations Office (DOE/NV) 325, Nevada Test Site Waste Acceptance Criteria (NTSWAC, current revision). Approval will be given by NNSA/NSO to generators that have successfully demonstrated through process knowledge (PK) and/or sampling and analysis that the Waste is low-level, contains asbestiform material, and does not contain prohibited Waste materials. Each Waste stream will be approved through the Radioactive Waste Acceptance Program (RWAP), which ensures that the Waste meets acceptance requirements outlined in the NTS Class III Permit and the NTSWAC

sustainable municipal Solid Waste Disposal in the belt and road initiative a preliminary proposal for chengdu city
Sustainability, 2018Co-Authors: Junhan Huang, Rui Zhao, Tao Huang, Xiaoqian Wang, Minglang TsengAbstract:The Chinese green Belt and Road initiative is promoted. This study takes Chengdu as a key hub under the Belt and Road initiative. The municipal Solid Waste Disposal is the point to control pollution and move toward sustainability. Hence, sustainable municipal Solid Waste Disposal needs to be studied. The prior studies are absent in the planning scenarios analysis. This study proposes a case study to propose three planning scenarios for Waste Disposal to enhance its sustainability. Scenario 1 represents the current Waste Disposal mode in Chengdu; Scenario 2 considers all the Wastes being incinerated; and Scenario 3 focuses on the incorporation of three Disposal methods, i.e., anaerobic digestion, incineration, and landfilling. These three scenarios are assessed based on their greenhouse gas emissions, costs, and public acceptance, to determine the optimality for future managerial practice. Results indicated that Scenario 3 has the highest overall efficiency, yet is challenging in terms of economic feasibility. The limitations of the study are also discussed.

Solid Waste Disposal methodology selection using multi criteria decision making methods and an application in turkey
Journal of Cleaner Production, 2017Co-Authors: Emre Arikan, Zeynep Tugce Simsitkalender, Ozalp VayvayAbstract:Abstract Rapidly increasing population, rising living standards and developments in the fields of science and technology cause continuously increase in the quantity and variety of Solid Waste. This situation results in a further contamination of natural resources. A variety of technologies for Solid Waste Disposal have been developed to reduce the detrimental effects of Solid Waste to a minimum level. In literature, studies that are focused on Solid Waste Disposal are generally considering thermal, biological, recovery methodologies or they are just devoted for Solid Waste technologies used in a determined country, city or region. Besides, in this study all alternatives that are currently used all around the world are investigated and suggestions are made based on the idea of possible implementations in Istanbul, Turkey. For that purpose, firstly overview definition and types of Solid Waste and general information about Solid Waste management were given. Afterwards, 10 Disposal alternatives of Solid Waste were evaluated via 18 criteria's which are determined by Istanbul Environmental Management Industry and Trade Co., Ltd. experts to select best Disposal technology. Three different multi-criteria decision making methods, Technique for Order Preference by Similarity to Ideal Solution – TOPSIS, Preference Ranking Organization Method for Enrichment Evaluations – PROMETHEE and Fuzzy TOPSIS were used for the selection. In this comparison current Disposal methodologies are evaluated and tried to determine the most feasible one. According to final results, ordered storing and burning systems are selected as top two methodologies for Istanbul case.

qualitative assessment of methane emission inventory from municipal Solid Waste Disposal sites a case study
Atmospheric Environment, 2004Co-Authors: Sunil Kumar, A N Mondal, S A Gaikwad, Sukumar Devotta, Rattan SinghAbstract:In developing countries like India, urban Solid Waste (SW) generation is increasing enormously and most of the SWs are disposed off by land filling in low-lying areas, resulting into generation of large quantities of biogas. Methane, the major constituent gas is known to cause global warming due to green house gas (GHG) effect. There is a need to study the ever-increasing contribution of SW to the global GHG effect. To assess the impacts, estimation of GHG emission is must and to avoid misguidance by these emission-data, qualitative assessment of the estimated GHG is a must. In this paper, methane emission is estimated for a particular landfill site, using default methodology and modified triangular methodology. Total methane generation is same for both theoretical methodologies, but the modified triangular method has an upper hand as it provides a time-dependent emission profile that reflects the true pattern of the degradation process. To check the quality of calculated emission-data, extensive sampling is carried out for different seasons in a year. Field results show a different trend as compared to theoretical results, this compels for logical thinking. Each methane emission-data is backed up by the uncertainty associated with it, this further strengthens the quality check of these data. Uncertainty calculation is done using Monte Carlo simulation technique, recommended in IPCC Guideline. In the due course of qualitative assessment of methane emission-data, many site-specific sensitive parameters are discovered and are briefly discussed in this paper.

a choice experiment analysis for Solid Waste Disposal option a case study in malaysia
Journal of Environmental Management, 2011Co-Authors: Othman JamalAbstract:In Malaysia, most municipal Wastes currently are disposed into poorly managed ‘controlled tipping’ systems with little or no pollution protection measures. This study was undertaken to assist the relevant governmental bodies and service providers to identify an improved Waste Disposal management strategy. The study applied the choice experiment technique to estimate the nonmarket values for a number of Waste Disposal technologies. Implicit prices for environmental attributes such as psychological fear, land use, air pollution, and river water quality were estimated. Compensating surplus estimates incorporating distance from the residences of the respondents to the proposed Disposal facility were calculated for a number of generic and technology-specific choice sets. The resulting estimates were higher for technology-specific options, and the distance factor was a significant determinant in setting an equitable Solid Waste management fee.
